The comments APIs are currently provided as a preview. Be aware of the following: * There might be unannounced breaking changes. * Any breaking changes to preview APIs won't produce a new [API version](https://www.canva.dev/docs/apps/rest-apis/versions/). * Public apps that use preview APIs will not pass the review process, and can't be made available to all Canva users. The `comments` endpoint allows you to create new top-level comments on designs and reply to a top-level comment thread. ## Comments APIs * [Create thread](https://www.canva.dev/docs/apps/rest-apis/reference/comments/create-thread/): Create a new comment thread on a design. * [Create reply](https://www.canva.dev/docs/apps/rest-apis/reference/comments/create-reply/): Reply to a comment on a design. * [Get thread](https://www.canva.dev/docs/apps/rest-apis/reference/comments/get-thread/): Get metadata for a comment thread. * [Get reply](https://www.canva.dev/docs/apps/rest-apis/reference/comments/get-reply/): Get a comment reply. * [List replies](https://www.canva.dev/docs/apps/rest-apis/reference/comments/list-replies/): List replies for a comment on a design. * deprecated [Create comment](https://www.canva.dev/docs/apps/rest-apis/reference/comments/create-comment/): Create a new comment on a design.
